A quick survey of the Internets shows this is frequent range of underground nuclear explosions. USGS reports the explosion a short while ago was on the surface.

Here is an interesting tidbit: "...a 5-megaton hydrogen bomb, detonated by the United States, and had a body wave magnitude of approximately 6.9 on the Richter scale. This was the largest underground detonation in history..." Source: https://www.scienceabc.com/eyeopeners/could-nuclear-bomb-testing-cause-earthquakes.html
